Headphone Damaging Frequencies!?

post #1 of 4
Thread Starter 
I am a proud new owner of a pair of Beyer Dynamic DT 770 Pro 80 headphones. I'm thinking, for the burn in process, of running certain frequency sweeps and pink noise through the headphones to really get them to sound as good as they can be.

Now I'll get straight to the point because most of you are probably sitting there thinking OMG another burn in question, why doesn't he just look at the other million billion posts on this site that discus this topic.

Well through a little bit of searching this site, I feel that those other posts don't answer my questions.

Now a lot of people have said that using low frequency sweeps for burn in can damage the drivers in your can's. Ok that's fine I can understand that. But those people have never really said what range of low frequency sweeps do the damage.

I'm sure your all familiar with Burn-in wave files: white noise, pink noise, frequency sweep, channel mix which has a load of sounds which you can use for burning in your can's. Now this site has some low frequency sweeps and other sounds and these are the ones that I'm thinking about using:

Frequency sweep (20-20000 Hz)

Low frequency sweep (20-200 Hz)

Heavy Drum (going down to about 20 Hz)

So some simply questions really, will these sounds played at a moderate volume do any damage to my can's?

If not, how long should I repeat the clips for them to effectively and positively loosen up the frequencies that they are targeting?

And if I can repetitively play the clips, how long a break should I give the can's until I can start to play these clips again?

One final question, these sounds won't hold back or take away any of the positive effects that the pink noise will be having on the headphones?

So thanks guys! I'm a brand new member to the site so please be kind. Look forward to hearing all your answers!!

If you keep sound to listening levels you will never damage your headphones.

And why not just listen? I've never gone through the break-in ritual with any headphone I've owned. I just listen to them and whatever happens is what happens. I'm not going to waste my time or listening time on it.

Thanks Erik. I have only known about this site for about five or so days, but I am already very familiar with your stance on the burn in process. Just to let you know that I don't just use the cans for casual listening but also for sound monitoring for recording. So really I need these to be working at their best as soon as possible. But anyway thanks for the comment.

I know burn-in is controversial but bare with me I'm just going to try to address some of these doubts the OP has.

Most people recommend playing somewhere between low-moderate listening, not moderate volume or higher. It'll theoretically make burn-in take longer or not be as complete but it's safer, you can decide to use higher volume later if you are unsatisfied with the results of low-mid volume burn-in.

The only explanation I heard for putting pauses between burn-in tracks to give them a rest is that the drivers build up heat which is not a very plausible reason to give drivers rest. I can't imagine how drivers could need "breaks", but it can't hurt to err on the side of caution, just do 5 minutes of burn-in, 5 minutes of rest, for as long as you want.

I think the main thing that happens with burn-in is a smoother sound. If you want more smooth bass, then do the low frequency sweep. But be careful not to overdo it or it might end up sounding too smooth for your tastes. I believe the same goes with pink noise, burn-in will smooth out the treble which may or may not be good, depending on your setup, headphones, and personal preferences. Always test occasionally to make sure you haven't overdone it, but generally speaking most people highly value smooth sound so maybe you want to burn-in 24/7 hehe.
